    D2 histosketch: discriminative and dynamic similarity-preserving sketching of streaming histograms

    Yang, Dingqi ; Li, Bin ; Rettig, Laura ; Cudré-Mauroux, Philippe

    In: IEEE Transactions on Knowledge and Data Engineering, 2018, p. 1–1

    Histogram-based similarity has been widely adopted in many machine learning tasks. However, measuring histogram similarity is a challenging task for streaming histograms, where the elements of a histogram are observed one after the other in an online manner. The ever-growing cardinality of histogram elements over the data streams makes any similarity computation inefficient in that case. To...

    Histosketch: fast similarity-preserving sketching of streaming histograms with concept drift

    Yang, Dingqi ; Li, Bin ; Rettig, Laura ; Cudré-Mauroux, Philippe

    In: 2017 IEEE International Conference on Data Mining (ICDM), 2017, p. 545–554

    Histogram-based similarity has been widely adopted in many machine learning tasks. However, measuring histogram similarity is a challenging task for streaming data, where the elements of a histogram are observed in a streaming manner. First, the ever-growing cardinality of histogram elements makes any similarity computation inefficient. Second, the concept-drift issue in the data streams also...
